Keep in mindIntermediate equipment and transport are not mapped in this summary. Read the setup notes before choosing hardware. Check the function table for supported controls and routines. A connection diagram does not establish every function or remote access.
This shows the connection route, not every network cable or a shopping list. One device may provide several roles, including a Matter controller and a Thread border router. Only a Thread connection needs the Thread role. Read the equipment cards for all recorded requirements.
These paths summarize documented setup options. Check the function table for the connection covered by each recorded capability.

Keep in mindUse Home Assistant’s HomeKit Device integration for the documented local alternative. Check pairing and supported functions for this route.
Check the function table and setup notes for this route. An alternative connection does not inherit every capability of the recorded primary connection. A Thread border router, a Matter controller and a platform home hub are different roles; suitable hardware may provide more than one.

Home Assistant's built-in ecobee integration lets you set the target temperature, and it reaches the thermostat through ecobee's cloud, checking it at intervals rather than locally. Home Assistant says its integration also changes the HVAC mode (heat, cool, auto and off); ecobee does not list that for the ecobee3 lite. The integration is community-maintained, and since Home Assistant 2026.3 you no longer need to register for an ecobee developer key. Local control is also possible through Home Assistant's HomeKit Device integration.[8][9][19][25][30][36][59]
One device can provide more than one role. These are setup requirements, not a shopping list of separate purchases.

A documented control or event is one part of a setup. It does not by itself establish a complete automation.
A platform connection does not confirm every function. Controls and reported events are shown separately from what an automation can use.
